Ever wonder who establishes internet protocols? In 1991, the Internet Engineering Task Force (IETF) recognized that the Internet would outgrow IPv4.  In early 1999, IETF created the IPv6 Forum to address the pending shortage of IP addresses and other limitations of IPv4. 

Four years later, a new Protocol was made ready for general availability.  In mid-2004, The Internet Corporation for Assigned Names and Numbers (ICANN) announced that the root DNS servers for the Internet had been modified to support both IPv6 and IPv4 (called ”dual stack”).
